I think your options are limited to Lilja, Pac-Nor, Shilen and Douglas. Krieger doesn't make a 9.3 in that contour in stainless. Bartlein, Brux, and Hart don't make them period. I'd probably lean toward Lilja since I have a .375 H&H with a lilja barrel that shoots tiny groups. I think Lilja could probably do it in under your time frame.
